Q. Who does a registered name actually belong to, the end user or the Registration Service Provider?

A. Domain names are not truly owned -- they're leased out on a first-come, first-served basis, and remain with the initial lessee until either a) the lessee does not renew the name, or b) a business with a trademark of the same name demonstrates a greater claim to the name than the lessee can demonstrate. The question is better phrased as 'who can control the domain name'. With Tiger-Direct-Domains.Com/Enom, the answer is the domain's Administrative Contact. This is usually specified by the registrant during the registration process.
